A new article from AHRQ identifies knowledge- and skill-based competencies that are necessary for investigators who conduct research within learning health systems. The new list of core competencies is a resource for health systems that seek to design, implement and evaluate researcher training programs. As defined by study authors, a learning health system researcher is someone who is “embedded within a health system and collaborates with its stakeholders to produce novel insights and evidence that can be rapidly implemented to improve the outcomes” of patients and health system performance. AHRQ authors divided 33 core competencies into seven domains of expertise: systems science; research questions and standards of scientific evidence; research methods; informatics; ethics of research and implementation in health systems; improvement and implementation science; and engagement, leadership and research management. The article, published in Health Services Research, was developed based on a literature review, interviews, surveys and input from three expert panels. Access the abstract.
